Greenheck SP-A90-QD Exhaust Fan

The Greenheck SP-A90-QD Exhaust Fan is a ventilation component to remove stale or contaminated air from indoor spaces, mounted in ducted or direct exhaust setups. It operates by drawing air from occupied areas and discharging it outside through an exhaust path and supporting continuous air exchange within the building, in HVAC systems. It is mounted in ceiling or duct configurations where controlled air removal is required. The fan assembly is used in residential and light commercial applications to maintain airflow balance and manage indoor air movement by expelling unwanted air from enclosed during system operation.
